Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

Introduction: Recently, Hayes et al. proposed novel designs for 12and 16-channel tongue coil arrays and demonstrated their ability to improve tongue SNR [1]. The coil array provides highly localized sensitivity that includes the tongue and upper airway. In this work, we measure and analyze the SNR and g-factor of the 16-channel tongue coil for several tissues of interest, in a mid-sagittal scan...

In this article, signal-to-noise ratio (SNR) criterion is investigated with the object of determining the level of its ability to distinguish between Event Related Potentials (ERPs) and noise signals in ElectroEncephaloGraphy (EEG) data. For this purpose a new algorithm (SNRMAX) based on SNR maximization and intended for extracting a linear subspace related to ERPs from EEG data is developed. T...

the purpose of this paper is to study the convergence and the almost sure t-stability of the modied sp-type random iterative algorithm in a separable banach spaces. the bochner in-tegrability of andom xed points of this kind of random operators, the convergence and the almost sure t-stability for this kind of generalized asymptotically quasi-nonexpansive random mappings are obtained. our resu...

To design a reliable wireless system, its energy efficiency is an essential factor. As MIMO system has to suffer from fading, interferences and noises, the system should design in such a way that to compensate these problems. So interference alignment is included with MIMO interfering broadcast channel. This paper deals with the energy efficiency maximization of MIMO-IFBC system. When the energ...

In this paper, an iterative method is proposed for solving the matrix inverse problem $AX=B$ for Hermitian-generalized Hamiltonian matrices with a submatrix constraint. By this iterative method, for any initial matrix $A_0$, a solution $A^*$ can be obtained in finite iteration steps in the absence of roundoff errors, and the solution with least norm can be obtained by choosing a special kind of...

OBJECTIVE We would like to improve the image reconstructions for both signal-to-noise ratio (SNR) and spatial resolution characteristics for the small animal positron emission tomograph YAP-PET, built at the Department of Physics of Ferrara University. The three-dimensional (3D) filtered backprojection (FBP) algorithm, usually used for image reconstruction, has a limited angle restriction due t...

In recent years, there have been many studies on integrating a number of heterogeneous wireless networks into one network by establishing standards like IEEE 802.16. For this purpose, the base station (BS) should allocate the appropriate bandwidth to each connection with a network scheduler. In wireless networks, the signal to noise ratio (SNR) changes with time due to many factors such as fadi...

The evaluation of the minimum distance of low-density parity-check (LDPC) codes remains an open problem due to the rather large dimension of the parity check matrix H associated with any practical code. In this article, we propose an effective modification of the error impulse (EI) technique for computation of the minimum distance of the LDPC codes. The EI method is successfully applied to sub-...
